Introduction:

This tutorial is trying to show how student can get access to the machines that allowing students to run the cadence software for their homework and project.

Cadence ( icfb ) is installed on in the particular sun workstations on SEASNET, and you will need to use any computer or workstations that has Xwindow software to access those sun workstations. In this tutorial, we are going to show you the methods: SEASNET lab PC, Your PC / Remote Desktop, Your PC / Exceed or some Other Xwindow Software, Linux PC.

Method 1 (recommended): Using Windows PC in the SEASNET LAB

For SEASNET LAB hours please see the following links

http://www.seas.ucla.edu/seasnet/Docs/quickref.html

Assuming you are physically sitting in the SEASNET LAB

As showing in the above figure, you click the icon xtelnet ugrad.eod

And then it will start up an big Xwindow login screen.

You have to type in your username and password.

Then you will see the following screen which you have a command line window.

At this point, you could use this as a terminal for the sun workstation.

For the terminal type, just press ENTER or type xterm.

You still need some windows manager function for the Xwindow desktop.

This allows you to move the application windows around.

There are two Window managers twm and mwm. Both of them are fine.

If you don’t have a preference, twm is recommended.

You need new terminal windows, click on Utilities > New Window

Up to this point, you switch to the sun workstation crenshaw (you can also use another machine exposition by replacing crenshaw:csh with exposition:csh)

After this, you can go back to Tutorial 1 to do what it says

To Exit the sun workstation

Execute exit several times in the first login session terminal.

Method 2: Using Your Own Windows PC Through Remote Desktop

Start > All programs > Accessories > Communications > Remote Desktop Connection

connect to remote.seas.ucla.edu

Then you can pretend that you are using the Windows PC in the SEASNET LAB

Method 3: Using Your Own Windows PC with EXCEED or Other Xwindow Software

You have to have your own Xwindow software, which can not be downloaded from SEASNET. Please refer to the manual from the software provider, and connect to ugrad.seas.ucla.edu.

Method 4: Using Linux PC in the SEASNET LAB or Your Own LINUX PC

For your own Linux PC, make sure you have set it up for remote Xwindow applications

Assuming you open a terminal window,

You just type

ssh ugrad.seas.ucla.edu

            it will prompt you to enter the password

            please keep the machine name in mind (for example: lindbrook)

            then the domain_name will be lindbrook.seas.ucla.edu

            after you login, type

setenv DISPLAY (domain_name):0.0

            for example setenv DISPLAY lindbrook.seas.ucla.edu:0.0

            for example setenv DISPLAY lindbrook:0.0

nsh

crenshaw:csh

After this, you can go back to Tutorial 1 to do what it says

To Exit the sun workstation

Execute exit several times in the first login session terminal.
